What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is given that Carpet costs $15 per square yard.

We need to find that How much will it cost to carpet a room that is 180 square feet.

Cost of carpet per square yard = 15 yard

We know that 1 yard  = 3 feet.

So, the Cost of carpet per square yard = 15

The Cost of carpet 3 square feet = 15

The Cost of carpet per square feet = 15/ 3 = 5 dollar

The Cost of carpet 180 square yard  = 180 x 5

= 950 dollar

Therefore, it will cost 950 dollar to carpet a room that is 180 square feet.

Answer:

  4/pi

Step-by-step explanation:

The area of the square is

A = s^2

The area of the circle is

A = pi r^2

The diameter of the circle is s, we need to find the radius

d = 2r

s =2r

Divide by 2

s/2 = r

A = pi *(s/2) ^2

A = pi (s^2/4)

We want the ratio of the A square/ A circle

                                          s^2/ pi (s^2/4)

The s^2 cancels

                                            1/ pi (1/4)

                                              4/pi

Answers

Cora got 85% of it correct so the decimal form would be 0.85
85/100 would be what she got CORRECT, and then 15/100 would be what she got INCORRECT. You can easily make them both decimals, because it is over 100, into .85 (the amount she got correct) and .15 (the amount she got incorrect).
